Making it about US, main concern is Baltics

I think the links there are less about 'wow look at how this disruption playbook worked in the US' and more about'look you can cause instability without inviting open warfare with NATO'.

Or are the Baltics and her people immune to propaganda?

Activating Russian communities is something different from promoting polarity in the US.

Sure, but they do the "promoting polarity" thing outside the US plenty. It's a useful tactic; pick wedge issues like gay people or immigrants, spread false or out-of-context news, etc.

For a nice Baltic example, Lithuania: https://www.thedailybeast.com/the-baltic-elves-taking-on-pro...

> Facebook is where the light skirmishes take place; the mortal combat is reserved for the comment sections of Lithuanian news articles, where the trolls loose a constant drizzle of falsehoods and complaints, each comment helping to construct an alternate reality version of life in this Baltic country of 3 million. Rather than a thriving and patriotic post-Soviet success story, which it is, the image the trolls cultivate is that of a demoralized and angry society whose people are ready for regime change, be it through internal democratic mechanisms or through “liberation” by a friendly neighboring army.

A playbook is made up of repeatable tactics.
